Why can't you calibrate an LCD to match film? Because LCD technology
isn't capable of reproducing the full contrast spectrum accurately.
Plasma and DLP televisions have the same limitations, although all
the technologies are getting better all the time. I'm sure one day
soon, LCD displays will match or best CRT displays, but not yet.

Since contrast is SO crucial in visual effects work (value being
much more important than color in the way human vision works),
I'm sticking with CRT's for now.
